We've a Halo Vortex 29 wheel, taped with Tesa Tape and running new valve. No damage or wobbles on rim.
We've got some Specialized Butcher BlkDmd 2.3's.
Two different tyres have blown off at 35psi when seating, one seated but then blew off a couple of hundred metres up the road.
The rim has had 2x Hans Dampf on before and has a Michelin Wild Enduro Gum-X on the front.
Do some tyre and rim combo's just not play ball?
No reply from Specialized yet - I had asked if they knew of any incomparably with certain rims.
Hmmmm.
Can I ask what hub you have on the vortex? Is it a Supradrive? I've had no end of issues with bearings collapsing on mine.
I've only ever run Maxxis on mine and never had an issue
Only time this has happened to me recently, I'd messed up the taping and gone a bit wide/deep on a shallow profile rim. Sure you've checked that already, but it does sometimes still catch me out, apparently!
That was my first thought.
We've retaped it - it's now got a double wrap, but only single layer at edges with double in middle as the tape is a few mm narrower that overall ID. All round the tyre can seat against rim wall and has alloy at base to sit against (of that makes sense!).
Supradrive
I'm not sure. I can say we've had it 6 months and the lad has put daft miles and jumps on it with not a problem.
Unlike the overpriced pile if steaming sh*te with no spare parts RaceFace and DILLIGAF attitude from RaceFace. Thankfully CRC agreed it wasn't good enough (pawl springs broke in 8 weeks, no spares available) and refunded our money. I'm not buying RaceFace ever again.
Do some tyre and rim combo’s just not play ball?
Yes unfortunately, they are all "standard", but some are at different ends of the standards and do not overlap well.
ERTO and ISO are both standards. You get tubeless rims with hooks and hookless. Some tyres are only for hooked rims. Hookless rims need tubeless tyres (or a tyre with a stiffer bead).
Some rim manufacturers list tested/approved tyres and incompatible tyres, some just say must be suitable. Enve released a list of tyres that were incompatible/unsafe to use with their road rims, the tyre manufactures said it was not their tyres, but Enve rims etc.
Most MTB tubeless stuff works, but some combos are a PITA.
In which case I've three Specialized 29er 2.3 Butchers to sell on....

Surely nobody will buy tyres that have blown off a rim? Beads likely shagged.
Aye, every chance they're gubbed, sadly.
Fark.
Can you try them on a different rim.
Worth trying, mibbe work with tubes, send the young test pilots out on them. 😆
Can you try them on a different rim.
Three 27.5 versions have stayed on Marin and a Mavic rim. A fourth Specialized(!) rim won't seat them properly, they've burped a few times this week.
I'm properly disappointed in the tyres, we spent £150 on them. I do wonder if the low sale price says something about the quality (or lack of).
To add to frustration, Specialized haven't replied to the email I sent.
Anyway, eldest is rocking new Schwalbe and Michelin for his Alps trip, and I've replaced the burping one with a spare HR2.
Anyone want some cheap Specialized tyres that you can't guarantee will run tubeless?
Also, what to do with two brand new but buggered new tyres? Upcycling ideas welcome.
I've had a very pleasant reply from. Specialized.
However they did suggest that pressures above 25psi might be responsible for the issue. The tyres have 25-50psi on the side.
Meh.
That's not a good enough response for me.
I have
1 29x2.6 butcher black diamond
1 29x2.3 slaughter grid
On raceface ar30 rims with pressures around 40psi
1 27.5x2.8 butcher grid
1 27.5x2.6 slaughter grid
On raceface ar40 rims with pressures around 30psi
All went up with no issues at all and have performed exactly as I'd expect.
I put ours on with the compressor, I have a small bottle of fairy/water spray for the sidewalls and blow them till they pop. Around 45psi. Then let them down to the required psi
29 x 2.6 front 22 rear 24
27.5 x 2.8 front 15 rear 17
They are on all but one of the bikes and never had a problem. All a mixture of carbon rims, Royal, Sixth Element and Nextie 29mm and 30mm internal. Not running any inserts.
Interesting reply from Specialized. I thought the idea of a max tyre pressure on the sidewall was the manufacturer had tested by inflating until failure point and then halved the failure pressure which is shown as max pressure and perfectly safe to use. So that Butcher shouldn't blow off until about 100psi.
Update: they have offered a refund on the three 29er tyres that won't stay fitted by themselves.
Fair play Specialized. Thank you.
Happy days. 👌🏻
Still waiting for the refund.
Frustratingly, the two lighter carcass Butchers on the front of two bikes are both leaking sealant through the sidewalls after 12 rides or so...
Are specialized tyres just crap?
No, they ain't, and to be fair there's a shit load of tyre brands that leak sealant, as rubber is porous.
Do specialized expect tyres to seat at 25 psi, nice of them to offer a refund but it's only what they should do if those tyres aren't fit for purpose.
Specialized have always been known for thin sidewalls. I'm not too bothered by a small amount of sealant leaking, particularly on the rear as the tyre gets older with a bit of sidewall wear. But the latest Butcher, mounted on the front, started pissing sealant all the way round on both sides pretty much straight away. Need to get around to returning it.
Perhaps even worse, the redesigned Butcher has much taller knobs than the old one. Resultingly the tread squirms about and feels very vague. This has been mentioned in a few bike reviews lately. Bizarre that the Ground Control and Purgatory are more confidence inspiring now.
Mibbe depends which version you use, I've a 2.6 black diamond butcher up front, it's anything but squirmy, very impressed with it. I bought it for the rear, but Its too big, so stuck it on the front for summer and took big Mary off for winter.
Sidewalls are definitely light on the control versions, it's the reason I've always used grid and now black diamond. Slaughter grid on the rear of the Bronson has had some abuse, and was flawless.
Yep, think the 2.6 has slightly wider and lower knobs so I can believe that one doesn't squirm.
Maybe Spesh tyres have slight inconsitency to them.. got my kid one of the 2.4 GRIDs to replace a knackered Mary (Purgertory, maybe) on Bontrager Line 30 rim, I never have had a tyre go on and inflate so easily since I stopped using Hutchinson.
So I get him a Slaughter GRID 2.6 for the rear and man that bastard would not seat, probably the [i]hardest[/i] job I've had seating a tubeless tyre ever. Took leaving it overnight with a tube in and using loads of soapy water (never had to use that before) to get the thing inflated. Stayed up now. I wouldn't be beaten.
The Grid's we have on the rear are good - they went up first time, stayed up and are not leaking through sidewalls.
Maybe it is the lighter front trail weight tyres that are oozing.
I'm enjoying riding them though - great grip, feel pretty supple and a nice predictable break away.
My latest tyres have been Specialized - bought in closing down sale of LBS - and I all but gave up on a couple - I thought the sidewall had perished - seemed to leak at various points from the off. Looked like it was especially bad in between the raised letters - which made me think the tyres were maybe just stored / folded too long. Now I'm not so sure it wasn't just below par tyres.
I've bought quite a few Specialized tyres recently and have been thoroughly impressed so far, they have all gone up easily with very little air leakage and haven't burped at all. They are all Grid casing but a mix of wheel size, tyre width and rim brand/width.
